Did you just want to look at what was available or were you looking for something specific....when I have ordered it has been from online stores that are specific to the lineage?I guess that's a long way of saying, what are you after?

I was just going to browse for now but perhaps it could be prints associated with the Nyingma lineage. I would like to get a photo of Vajarsattva (approx. 5*7), and perhaps eventually a poster of Padmasambhava and Chenrizig which I would eventually frame.

you know, you can do a google image search and specify that you want only "large" images - high res for beautiful printing. if you don't have a printer, you could always get it printed at a print store. you will have more image choices that way.
